多钢种混用钢梁滞回性能试验研究与有限元分析

Jianzhu Gangjiegou Jinzhan
设计制作了4个H型钢梁试件，通过拟静力试验得到不同腹板高厚比以及钢种组合下钢梁的破坏形态、滞回曲线、骨架曲线以及延性等，从而评价试件的滞回性能。随后利用有限元软件ABAQUS进行模拟验证，通过参数分析进一步补充不同腹板高厚比和钢种组合对钢梁滞回性能的影响。结果表明：随着腹板高厚比的减小，钢梁的延性和耗能能力均有所提高，且增大腹板厚度对钢梁延性的提高程度大于极限承载力的提高程度；相比同钢种钢梁，多钢种钢梁极限承载力提高了17.4%，延性降低5.6%。随着多钢种钢梁翼缘强度等级的增大 ...

翼缘卷边蜂窝开孔PEC梁抗震性能研究

Jianzhu Gangjiegou Jinzhan
针对PEC梁力学性能及施工过程中的薄弱点，本文提出了将PEC梁翼缘卷边并在腹板开设蜂窝孔的构造。考虑剪跨比与箍筋间距因素的影响，对3根不同剪跨比与箍筋间距的翼缘卷边蜂窝开孔PEC梁进行了拟静力试验。观察了试件不同加载阶段的破坏特征以及荷载-位移曲线，根据试验数据分析试件的各项力学性能指标。试验结果表明：翼缘卷边蜂窝开孔PEC梁具有较好的承载能力与延性，破坏模式是根部混凝土开裂压溃和翼缘卷边屈曲撕裂；剪跨比主要影响试件的承载力、刚度退化，箍筋间距主要影响耗能能力，两者对裂缝发展都有较大影响。
